The nominal compaction density was not pucified by BPIL but was determined from the average density of the fuel rods fabricated. It was 1 specified that the rods will have a fuel density of +2% of this determined average density and the density within a fuel rod will be 2% of the average for that fuel rod. Based on experience with depleted (U, Th)o, in the "cold" operation of the facility, an average density of 90% of theoretical was expected and was obtained using (Th-3 wt . 2330)02: NE The cone-shaped Zircaloy-2 bottom fitting, which will be used to . direct the rod lo the critical lattice it , is welded onto the tube . 10 a gas tungsten-arc welding operation, which is done outside the facility. The annular groove in the bottom plug is used as a handling aid during fabrication. In the facility, the top plus, cerumic spacer, and spring are inserted into the fuel tube after compaction as a unit. The ceramic spacer and spring are used in the void area at the top of the fuel rod to - - prevent redistribution of the fuel during hanriling.

Through ie AB . - - recycling of the +6 fraction and judicious charging of the ball mill with the 6+16 and -16, sufficient amounts of course and fine powders consisting *- of 55% -6+16 and 45% unclassified fines are produced. The development of the process to produce the fine fraction will be considered in the "cold" operation section. The two fractions are then separately weighed out on a automatic batch weigher, blended in a "v" blender, and using a vibrating feeder, fed into the rods. The powder is diensified using an air driven . . . vibratory compactor during feeding followed by additional densification .'-' V .- . -' . with a weighted rider rod resting on top of the fuel column. The end cap, - spacer, and spring are then p.l.uced in the roi iind the end closure weld made. Next, the rod is ultrasonically cleaned and summa scanned to determine the density fluctuations along the long axis. The welds are then helium leak checked and the rod smeared and cleaned until the smear count is < 2000 dis/mn. Mnally, the rod is loaded into the carrier for shipment. P .".

A number of alterations, 27.justments, repairs on the vibratory compaction equipment (Fie. 5) were requirei. m'he polyurethane dust boot between the vibratory feeder tube and the unnel was removed so that the powder feeding into the rod could be obscrviAlthough this increased the dusting in this area, it wis i'ound that t!ic Teed rate could not be adequately controlled unless the strean was observed. After the high forces, imparted by the vibrator, broke the rac':, the rock and pinion gear static- load rider rod was replaced with a weichter moi. The comactuated sliding taper jaw chuck also suffered from these slm... forces and was replaced with a chuck consisting of a slightly modified W ok coupling.

The mechanical forepump operated continuously for more than eight months when the seals seized, requiring replacement. The density scanner (F1€. 7) performeri aricquately but not up to the dasa.in expuebliniad quality expected when designed. The instrumentation was provided with an integrator circuit to measure the area under the plotted density curve thereby allowing the bull: density of the fuel bed to be determined. The output of the detector-photomultiplicr Wils found to be unstable over a long period of time which would not allow the integrator to establish a base Une for measurement. The cause o: this instability is still being debated. The density variation within the fuel column was determinca by running a set of standards with each rod and coinparing the standards with the rod. Two typical scans are prescntc:'in Fig. 8. The separation between the standards is used to determine the number of chart divisions over which the fuel column scon may range and still meet the specification of 12% of the bulk density variation within 21 individual rod. .- = ---- - 24 -2,- 2 .33.77-**.. * - ME . - - - - - - - - .. - : N ' !
